The Combined Defence Services (CDS) exam, conducted by the Union Public Service Commission (UPSC), is the gateway to the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers’ Training Academy (OTA). The exam tests candidates’ knowledge in areas like English, General Knowledge, and Elementary Mathematics. Here’s a detailed breakdown of the exam pattern, marking scheme, and preparation tips.

Candidates applying for the IMA, INA, and AFA have to take a written test consisting of three papers:
